According to the balanced chemical equation below, how many grams of CO2 would be produced from 20 grams of C3H18 and excess O2?
2 C3H18 + 25 O2 --> 16 CO2 + 18 H20

Hno3(aq) → h+(aq) + no3−(aq). picture ii best represents the strong acid hno3. strong acids are strong electrolytes

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf
